Charlie Williams regularly performs children’s programmes in Seattle schools. One of the shows is a science presentation about clouds aimed at first graders and is called “The Loudest Cloud” which encourages the children to look at the different cloud personalities. He has very kindly offered to share this as a resource for our members and we hope you enjoy it as much as we did.
